Note:
1. AWG wire rating derived from MIL-W-5088B.
2. Ampacity of aluminum wire is approximately 84% that of copper wire.
3. With bundled wires, use the following percentages of the rated ampacity:
2 conductors 94% 4 conductors 83%
3 conductors 89% 5 conductors 76%
4. Maximum temperatures. ambient = 50° C; conductor = l05° C.
Output Isolation
The output of the power supply is isolated from earth ground. Either output terminal may be grounded, or an external
voltage source may be connected between either output and ground. However, both output terminals must be kept within
±240 Vdc of ground. An earth ground terminal is provided on the rear panel for convenience, such as grounding wire
shields.
The earth ground terminal on the rear panel is a low-noise signal ground for convenience only. It Is not
designed to function as a safety ground.
